azure - 尝试使用 ARM API 获取 token 时未授权

Question

我尝试使用Azure Resource Manager API获取 token ，但得到401-Unauthorized响应。我的代码如下:

var client = new HttpClient();
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue(
   "Basic",
   Convert.ToBase64String(
       System.Text.ASCIIEncoding.ASCII.GetBytes(
           string.Format("{0}:{1}", client_Id, client_secret))));

var content = new FormUrlEncodedContent(new KeyValuePair<string, string>[]{

            new KeyValuePair<string, string>("grant_type", "client_credentials")
        });

content.Headers.ContentType = new MediaTypeHeaderValue("application/x-www-form-urlencoded");

var response = client.PostAsync("https://login.windows.net/subscriptionId/oauth2/token", content);

根据您的代码，您可以引用以下代码来获取您的token:

var client = new HttpClient();

var content = new FormUrlEncodedContent(new KeyValuePair<string, string>[]{
    new KeyValuePair<string, string>("resource", "https://management.core.windows.net/"),
    new KeyValuePair<string, string>("grant_type", "client_credentials"),
    new KeyValuePair<string, string>("client_id", "{ClientID}"),
    new KeyValuePair<string, string>("client_secret", "{ClientSecret}")
});

client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
var response = await client.PostAsync("https://login.windows.net/{TennantID}/oauth2/token", content);

Console.WriteLine(await response.Content.ReadAsStringAsync());

结果:
